Gregory Wrightstone, Executive Director of the CO2 Institute, talks with Jacki about his new book:  A Very Convenient Warming: How Modest Warming and More CO2 are Benefiting Humanity (foreword by Dr. William Happer, Professor Emiritus, Dept. of Physics, Princeton University). Mr. Wrightstone argues that modest warming and increases in CO2 lead to a thriving planet and actually saves lives through longer growing seasons, enhanced crop yield, and a history that shows civilizations thrive in warming periods. This book follows up Greg’s last book, a best seller that remarkably hit #1 multiple times: Inconvenient Facts: The Science Al Gore Doesn’t Want You to Know.
